Patent GB-771389-A (GB)
Title: Electrical h.f. waveguide device
Inventor: THOMPSON GEORGE HORACE BROOKE
IPC: H01P1/365
Filed: 1955-02-03
Abstract: 771,389. Waveguide accessories. STANDARD TELEPHONES & CABLES, Ltd. Feb. 3, 1955, No. 3178/55. Class 40 (8). A waveguide device having non-reciprocal transmission properties comprises a circular metallic waveguide tube 2 having a filling 3 of. high-resistance ferromagnetic material and means (e.g. a solenoid 8) for subjecting the filling to a steady axial magnetic field, the cross-section of the waveguide being such that with zero axial field it is dimensioned below cutoff for transmitted energy at the highest desired frequency of operation. The waveguide 2 is connected by known mode-conversion means to input and output rectangular guides 1, 5. Two quarter-wave dielectric plates 6, 7 arranged respectively at +45 degrees and - 45 degrees with respect to the plane of polarization of the input energy convert this energy to a circularlypolarized mode within the circular guide 2. It is stated in the Specification that for wave energy polarized in the positive sense (i.e. in the same direction as the current in the magnetizing solenoid 8 looked at in the direction of propagation) the normal cut-off characteristics of the ferrite-loaded guide are reversed, i.e. the guide will propagate only when the frequency is less than a certain critical value referred to as the " inversion frequency." By choosing guide dimensions such that the ordinary critical or cut-off frequency is greater than the highest frequency to be passed and adjusting the axial magnetic field for ferro-resonance (giving high attenuation) at a frequency lower than the lowest frequency to be passed and for inversion at a frequency higher than the highest frequency to be passed a kind of band-pass filter is obtained. Energy propagated in the opposite direction is polarized in the negative sense and remains highly attenuated throughout the frequency range for all values of axial field. The filter is, therefore, non-reciprocal. The ferrite filling of the guide may be magnetically conditioned to a state in which the effective transverse permeability is negative and by varying the intensity of the magnetic field a variable phase-advance may be obtained. The Specification contains a detailed discussion of the theory of the invention.

Abstract: 836,117. Generating combustion products under pressure. ROLLS-ROYCE Ltd. Feb. 4, 1957 [Feb. 2, 1956], No. 3381/56. Class 51 (1). Combustion equipment of a gas turbine engine comprises a flame tube disposed within an outer air casing, a fuel injector being provided to inject fuel into the upstream end of the flame tube. The flame tube has at each side of the local centre line of the combustion space air inlet means adapted to direct into the combustion space a plurality of streams of air having a component of velocity in an upstream direction to meet in the region of the local centre line, the air streams from each respective side of the local centre line being directed to meet at a point short of the local centre line so as to produce an air stream which is flattened in cross-section to reduce the risk of this air stream missing the flattened air stream from the air inlet means on the opposite side of the local centre line. The combustion equipment shown comprises an annular flame tube 24, 25 disposed within an outer annular air casing 22, 23, a fuel injector 20 being disposed within the upstream portion of the flame tube 14, 15 and injecting through an aperture 21 in a ring member 17, the flanges 17a, 17b of which are spaced from the walls of the flame tube by corrugated spacers 18, 19. Pairs of U-shaped scoop members 31, 34 in nested relation are disposed on the outer surfaces of the flame tube walls, the scoops facing into the air streams flowing between the flame tube and outer air casing. The scoop members 31 are curved at their downstream ends to enter orifices formed in the flame tube wall sections 24a, 25a, the adjacent portions of the flame tube wall sections being curved inwardly at 33. A curved tubular member 36 is disposed within each scoop member 34 and extends through an opening in the flame tube wall section 24a, 25a. The air streams from each pair of scoops converge at a point which lies short of the local centre line 30 of the combustion space. The air streams from the scoops at each side meet adjacent the centre line. The cross-section through the scoops in this embodiment is constant whereby velocity of the air streams remains constant. In a second embodiment, annular scoops are disposed on the outer surfaces of the flame tube walls, the crosssectional area of the scoops increasing in the direction of air flow. Short pipes directed in an upstream direction lead from openings formed in the flame tube wall at the downstream end of each scoop, the air streams from each pair of pipes converging at a point short of the local centre-line of the combustion space. The invention is also applicable in the case of combustion equipment comprising tubular flame tubes disposed either each in its own tubular air casing or a plurality thereof disposed in an annular air casing. Specifications 744,593, 744,657 and 744,659 are referred to.

Title: Improvements in or relating to the preparation of ª‡ª‰-unsaturated aldehydes
IPC: C07C47/225
Filed: 1938-02-03
Abstract: 512,465. Aldehydes. BURKHARDT, G. N., HEILBRON, I. M., and ALDERSLEY, J. B. Feb. 3, 1938, No. 3457. [Class 2 (iii)] alpha-#-Unsaturated aldehydes are obtained by the oxidation at the double bond, by means of ozonolysis, of substituted or unsubstituted allyl carbinols, so as to form #-hydroxyaldehydes, and removing the elements of water from the latter. The alpha-# compounds are usually accompanied by #-gamma compounds, which may be separated therefrom by fractional distillation. The substituted allyl carbinols employed as parent materials include compounds in which one or more.aliphatic, aromatic, hydroaromatic or heterocyclic residues are attached to the carbon atom of the carbinol group, and also compounds in which the said carbon atom forms part of a ring, e.g. 1-allylcyclohexanol. The removal of water from the #-hydroxyaldehydes largely takes place spontaneously during the ozonolysis, but may be completed by means of a dehydrating agent, e.g. iodine, phosphorus pentoxide or acetic anhydride. In examples, (1) ozonised oxygen is passed through a solution of 1-allylcyclohexanol in glacial acetic acid till no more is absorbed, the solution is then warmed with zinc dust, heated with water to decompose the ozonide, extracted with ether, and the ether extract is fractionated to produce cyclohexenylacetaldehyde, cyclohexylideneacetaldehyde, and #-hydroxycyclohexylacetaldehyde ; the latter product is distilled with iodine to give further fractions of the unsaturated aldehydes, and (2) dimethylallylcarbinol is similarly treated ; the main product is #-methylcrotonaldehyde.
